NOTE:
There will be little or no flow through the product line at this time.
5.Make sure that the RO power switch is in the OFF position. Plug the power cord into a 115 VAC grounded outlet. Do not use an extension cord or an adapter.
6.Ensure the dialyze/flush valve is in the dialyze position.
7.Turn the RO power switch on and run the system for 30 minutes. Observe displays and note stabilization of rejection and TDS.
8.After a minimum of 3 hours run time, disinfect and rinse the RO unit with an approved disinfectant before using for hemodialysis treatment (refer to Chapter Four for instructions on disinfection).
WARNING:
After disinfection, the product water must be verified free of residual disinfectant.
WARNING:
Ensure that TDS and membrane performance (% rejection) are normal for the regions water quality. Consult your facility physician. An AAMI analysis and bacteria test of the product water must be obtained and interpreted before using the RO unit for hemodialysis treatment (refer to the Product Water Analysis procedure and the Product Water Culture Procedure).
CAUTION:
New RO units with thin film (TF) membranes must be rinsed to drain with normal pressures for a minimum of three (3) hours before exposure to disinfectants such as Renalin and a minimum of six (6) hours before exposure to formaldehyde.
NOTE:
Ideally, rejection will be 95% or greater. If less than 95%, extend rinse period an additional 30 minutes.
9.Close the product valve and remove the product rinse extension line. Connect product line to inlet line on the dialysis machine. Open the product valve.
10.Start the dialysis machine into a rinse cycle.
11.Set the product water TDS alarm limit switch as prescribed by the physician. The switch is normally set to twice the initial TDS reading (or “next higher” setting) at
WARNING:
The TDS alarm limit should not be moved from this setting unless instructed by a physician.
